Airmax Pond Dye

I have a 1500 gallon gold fish pond and a 7000 Koi pond that were looking a little sad and brown here in winter. And since the water clarity was good I was concerned about the views that might be open to heron, raccoons, possums. Yes I live in the city but have a nice woody acre. So I decided to try the Airmax Black Dye because the blue dye doesn't look good on waterfalls. Well the black is very pretty black with very little product used, but the water coming over the waterfalls looked neutral. That was good. The water in the test tubes for ammonia, nitrites, pH etc was clear so that tests were accurate. That is good. I hope that the lack of penetrating sunlight may slow down string algae as it warms up. But the darkness does not seem to affect water temp. Thats good. And the ponds looked really cool, deep black with the reflection the ads talked about. Until I decided to put some Natures Blue in one to try to get the Twightlight Blue that Airmax also makes but that I didn't buy. Unfortunately it did what ll blue dies did: make it a very pretty but unnatural blue across the waterfall and at the agitation at the bottom of the falls. When I received the products there was a slip enclosed that asked that if I could't give them 5 stars please call or email. I had 2 issues that were going to take my rating to 4 stars so I did as asked and emailed them my feedback. Much to my surprise I didn't get a defensive answer or an excuse as to why they must do what they must do. I got a real back and forth conversation that specifically addressed the feedback I was going to give about dosing for smaller ponds. As a result of the time and interest they took with someone who only spent about 50.00 with them, they have created a repeat customer. So my feedback is that the product is good but use increments of a half or one ounce at a time. If you have a waterfall the Natures Blue will make it look very blue...very bright blue, and I think unnatural. I am going to stick with Black or try Twilight Blue. Thanks Steve! You were a Blessing.

We love this dye, and the fish love it too. When the dye is in, the fish can be seen clearly swimming high on sunny days, as the water is shaded nicely for them. It also keeps down the algae. We were paying $300 a month for a lake maintenance company to manage our spring fed 1 acre pond. Then we decided to diy it. This color is much prettier than the one the maintenance company used. We now also get our algeacide from Amazon...treat it with that every 2 weeks....just like the company did, then apply this once a month. A full bottle for our 1 acre. This system has saved us so much money! The algeacide we use is the $35 one. Great diy combo for crystal clear, pristine water. It turns out pond into a tropical paradise! It actually lasts longer than a month! As it starts to fade a bit, I retreat. I prefer mine very colored. You can go months before adding. When you get lots of rain, you will need it a bit sooner. It's safe for our fully stocked pond, and we even have foot long goldfish, and it's safe for them all.

Added to 1 gal of water and pump sprayed around pond. Pond is approximately 3/4 of an acre. Really pretty the next morning.

We've only had a pond for a year now and learned from the previous owner about this product. It wasn't until Jun 2025 that I put in our first application. I added one more 4 mo later; before the winter. So it's a little early to judge if it's doing everything it's supposed to, but it certainly did make the pond blue! Before and after pics attached.

(In case you don't read the full review: My dad tried several other name brands of pond dye, but he still had algae blooms throughout the spring and summer. This product also contains beneficial bacteria to clear the water, and I had zero algae in my pond and zero affect to the fish. Getting a 2-in-1 product saved me $ and yielded better results than just dye.) I have a stocked 1/2-acre pond that's 40 years old. The summer of 2020 started hot early, resulting in a major algae bloom, with half the pond covered. I got a professional algae treatment, but further treatments would cost $300 a month. After doing a lot of research, I chose this product (Nature's Blue color) from reviews, and because it was budget friendly. I poured half of the gallon along the edges of the pond, and let it disperse naturally. The color wasn't as rich as I was hoping for, but I was eyeballing it, and likely didn't use enough product for the pond size, as the pond is 12 feet deep, and the instructions cite a 6-foot depth. I didn't have one spot of algae the entire 2020 summer, which turned out to be one of the hottest on record. So, success! I used the second half of the gallon about 8 weeks later (August) when I noticed the color disappearing. It's now late November 2020, and my pond still has a soft blue color. Most importantly, the pond was absolutely no work because this product gave me a 100% clean pond from spring right into winter. And no harm to the fish. UPDATE: This pond dye really sticks. I live in a cold winter state. When the pond froze over on occasion, it was a beautiful light blue against the white snow. Now here it is late April 2021. The pond expert told me that many of his clients already have half of their ponds covered with algae due to the early hot days this spring. My pond is still clear of any algae -- from last year's fall treatment. I had bought the Plus version with beneficial bacteria.

This product did help to keep the algae down but made it harder to see the fish until the came to the surface

LOVE this product. i poured 1/3 of bottle into our pond and within 20 min our pond was a gorgeous blue color and with in a couple days it was crystal clear. I have enough to do some treatments in the spring again. I will definitely buy more

Packaging not suited to the product. All four packets were spilling into the plastic bag holding them. One should not only wear disposable gloves, as noted on the packaging, but preferably gloves to the elbows and a long plastic apron to handle the packets. Due to the inner packets being broken, the loose product got on my arms and clothes. The product permanently stains whatever it touches and the stain is not soap and water soluble. You have to wait for you skin surface to wear off naturally before you'll get rid of the stains. The packaging says to use diluted bleach on clothing ... that still removed the colour of my jeans. I'm too old to find the bleached jeans look attractive. 😄

Love this product for out pond. Use caution because a little goes a long way .

I have used this product for a couple of years and it really works well to get rid of the algae. We have a large, deep pond and it protects the fish from the herons as well. The water has a nice deep blue color. It was delivered on time with no problems.
